Description

Unmanned aerial vehicle's blade protection device Technical Field The utility model relates to the technical field of unmanned aerial vehicles, in particular to a blade protection device of an unmanned aerial vehicle. Background The protection casing of current unmanned aerial vehicle adopts the fixed mounting mode to cover in the blade outside generally, and its structure can produce showing the interference to the air current in unmanned aerial vehicle flight. When the blade rotates, the air needs to bypass or pass through the fixed structure of the protective cover, so that the air resistance around the blade is increased, the flight efficiency of the unmanned aerial vehicle is directly affected, and the flexibility of the unmanned aerial vehicle is reduced. Therefore, the structural defect of the conventional fixed type protective cover has become an important bottleneck for restricting the performance improvement of the unmanned aerial vehicle, and there is a need to design a foldable protective cover so that the foldable protective cover can be unfolded to provide protection when needed, and folded and retracted in the flight process to reduce air flow interference, so as to balance the protection performance and the flight performance. Disclosure of utility model The utility model aims to provide a blade protection device of an unmanned aerial vehicle, which can solve the problems in the background.
